9:3 Pull Height
The Deep Digger pull features hydraulic pitch
control for precision operation. However the
pull and the pitch control mechanism must be
set up to work in the optimum position so that
full adjustment is available to the operator.
When the ripper is working at the required
depth, the optimum position of the pull is
sloping up towards the tractor.
There is an adjustment available to achieve
this.

9:4 Pull Tongue Height
It may be necessary to move the tongue up
or down to achieve a level pull. To set the
correct working position of the pull, follow the
instructions below:
1. Choose a level site for the ripper and
tractor for adjusting the pull tongue.
2. Lower the ripper so that the tynes are
resting on the ground, and the wheels are
resting on the ground.
3. Disconnect the pull from the tractor, using
the Pitch control hydraulics raise the
pull to clear the tractor, move the tractor
forward so that the tractor drawbar clears
the pull. Raise / lower the pull so that is is
sloping slightly down towards the tractor.
4. 4 Remove the pull tongue and replace at
the height of the tractor draw bar tighten
the bolts to 274 ft/lbs
5. 5 Reconnect the tractor.
6. Test at working depth the pull should be
sloping up towards the tractor.
Whenever a different tractor is used
with the Deep Digger, it is absolutely
essential to check the pull height
is correctly adjusted. Failure to
adjust the pull height correctly may
adversely affect ripping performance.
The initial setting up of your ripper
behind a tractor is critical to its
correct performance.
IMPORTANT!
Pull Tongue adjustment
Always use a torque wrench on wheel nuts and
gang bolts, over-tightening will damage threads.
